Received a call. They left no voice mail. When I called back I got a busy signal.

We don't answer any calls we don't know, regardless of the area code but especially any 800, 888, 9**.  Not even familiar with a 949 area code.  No message but can believe this to be a telemarketer or scam call.  Easy answer: if you don't know the number, don't answer. If it's important, they will leave a message.  If it's a scam or telemarketer and they leave a message, delete it."

same as everyone elses, no voicemail left, dont recognize the #, will not answer.

Same as the other 5, call came in about a minute ago...

Automated message about diabetic supplies.
